Subject: [Sip-implementors] Cseq with PRACK and reinvite

Hi All,
  See the scenario:
    A                 B
    ----INVITE-------->        CSeq = 1
    <----RINGING------
    -----PRACK-------->        CSeq = 2
    <----OK(PRACK)----
    <----OK(INVITE)---
    ---ACK(INVITE)---->
    
     ----ReINVITE----->       CSeq = 3
    <---OK(ReINVITE)---
    ----ACK(ReINVITE)-->
    ----BYE---------->        CSeq = 4

Second Scenario:

    A                 B
    ----INVITE-------->        CSeq = 1
    <----RINGING------
    -----PRACK-------->        CSeq = 2
    <----OK(PRACK)----
    <----OK(INVITE)---
    ---ACK(INVITE)---->
    ----BYE---------->        CSeq = 3
     
    
Is this behaviour right in terms of Cseq ? Please Comment.

Thanks in Advance.

Regards,
Parveen
